IPC: C02F11/14
Filed: 1980-09-25
Abstract: PURPOSE: To obtain cake having a low water-retaining rate at a high speed, by adding clay and then a flocculant to sludge to form coagulating flocks, and thereafter dewatering the mixture.  
     CONSTITUTION: Clay is added to water-retaining sludge, and then a high molecular flocculant is added to form coagulating flocks. thereafter, the treated water-retaining sludge is dewatered. The clay to be used in this process is preferably one in which about 70% or more, especially 80%, of particles have sizes larger than 65 meshes. The clay is preferably added at a rete of about 30W40% against solid matters in the sludge. According to this treatment, the sludge can be efficiently dewatered by using small amounts of additives only.

Title: Plural-call connection control system
Inventor: SAKUMA SHUICHI
Filed: 1985-06-18
Abstract: PURPOSE:To set plural calls at the same time to a nonprocedure terminal device by providing a plural-call setting information means, a transmission request call identification means and a data reception call informing means to a packet exchange having a packet composition decomposition mechanism and accommodating nonprocedure terminal device. CONSTITUTION:Plural calls incoming/outgoing to/from a nonprocedure terminal device 4 are set in parallel to a plural-call setting notice means 31, identification information is given to each set call and informed to the terminal device 4. In receiving a data transmission request added with identification information from the terminal device 4, a transmission request call identification means 32 sends a data sent from the terminal device 4 as a call corresponding to the identification information. When a data relating to a call being set by the device 4 is incoming, a data reception call notice means 33 transmits the reception notice added with the identification code given to the call to the device 4 and sends the data to the terminal 4. Thus, plural calls are set in parallel to the device 4 to improve the device to the nonprocedure terminal devices.

Abstract: PURPOSE:To facilitate the weight analysis and the designing carried out based on this analysis result by displaying a two-dimensional graph on a display screen to plot the change of a model centroid position and then performing the simulation to change the centroid position on the graph. CONSTITUTION:A unit shape file 6 stores the shape data on the units forming a model, and a mass property file 7 stores the properties of the centroid position data on each unit and the mass property data on the weight data. Then the centroid position of the model is calculated based on the mass property data, and the model design values are plotted and displayed on the two-dimentional coordinates set on the X and Y axes. Furthermore the unit having the least weight change is discriminated when the centroid position of the model set on the coordinates is moved by an optional extent. At the same time, the model design value is changed in plural steps and by each prescribed shift extent. Then another means calculates again the centroid position of the model for each step change end shows the centroid position on a graph.

Abstract: PURPOSE:To realize a surface light-emitting laser enabling continuous oscil lations at room temperature by reflecting laser beams, which are emitted from a semiconductor laser element and projected to a photodetector, by an inclined end surface in the photodetector and changing the direction of laser beams. CONSTITUTION:A semiconductor laser takes an internal striped type in which an N-type GaAs current block layer 9 is formed onto a P-type GaAs substrate 2, currents are concentrated to a V groove section from which the block layer 9 is removed, and laser oscillations at a low threshold are conducted by an active layer 4 just above the V groove. Since the semiconductor laser has a P-N junction consisting of a P-type clad layer 3 and an N-type clad layer 5, the same structure is also used as a photodetector. Laser beams emitted from an end surface oppositely faced to the photodetector of the semiconductor laser are reflected by an inclined end surface in the photodetector, and projected in the direction vertical to a substrate surface. Photocurrents are generated by partial beams simultaneously projected to the photodetector, and monitor signals are acquired.

Title: Washstand equipped with soft soap feeder
Inventor: ICHINO MASARU
IPC: E03C1/046
Filed: 1990-05-23
Abstract: PURPOSE:To supply aqueous soap in exceedingly simple manner when soft soap is supplied into the tank on a washstand by forming an aqueous soap supply port on the side surface of an erection wall and connecting the supply port and the tank through pipings. CONSTITUTION:A supply port 38 for supplying soft soap into a tank 30 is formed on the side surface of a back guard 16. When the soft soap is discharged from a nozzle 18, the rest quantity of the soft soap in the tank 30 reduces, and the weight of the tank 30 reduces. Accordingly, the tank 30 is gradually raised by the pushing by a spring 58, and when the quantity of the aqueous soap reduces less than a prescribed quantity, a projection 68 hits an upper limit switch 66, and an ON signal is inputted into a controller. Then, a supply lamp 48 comes ON, and the demand to supply the soft soap into the tank 30 is displayed (alarmed). In this state, even if a sensor 24 detects a hand, a pump 32 does not operate, and the idle operation of the pump 32 is prevented. Accordingly, the conspicuous existence of the supply port 38 and a cap 46 is prevented, and the outside appearance is improved.

Title: Recording and reproducing device
Inventor: SAKATA TSUGUHIDE
IPC: H04N5/94
Filed: 1989-05-25
Abstract: PURPOSE:To reproduce a color image signal without being affected by a dropout by adding an index signal when detecting the dropout in a reproduced and compensating the dropout of the signal to which the index signal is added. CONSTITUTION:A luminance signal of one screen plane is reproduced from a recording track and when the dropout generated in the reproduced signal is detected, the reproduced signal is stored together with the added index signal; when the stored signal is read out, the dropout of the signal to which the index signal is added is compensated and the signal is outputted. For example, when image data are read out, a memory control circuit 234 decides which scanning line a data group where the dropout is generated corresponds to by detecting whether or not an error flag is set on a frame memory. Consequently, the dropout compensation is easily performed without adding any new memory.

Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a waste sterilizing treatment device of a type having a sterilizing treatment chamber to treat infectious waste from a hospital, a clinic or the like. SOLUTION: Infectious waste from a hospital or the other generating source is sterilized and treated in a chamber 14 rotatable between a waste loading position, a sterilizing treatment position and a waste abandoning position. The chamber 14 is installed on a frame structure body 21 by first and second paired rotary arms joined to side parts of the chamber 14 in separate positions. An actuator moves the chamber to the loading position by turning the first arm upward, and rotates the chamber to the abandoning position by turning the arm downward. By arrangement of the arms, the whole chamber descends when rotating toward the loading position, and ascends when rotating toward the abandoning position.  Therefore, an ascending distance of a material necessary in a loading process can be shortened, on the one hand, a sufficient clearance can be obtained under the chamber because of an abandoning process.
